Hadith 8:501
Abu Bakr narrated to us, he said: Abda narrated to us, from Hisham, from his father, that Umm Salama said: "O Messenger of Allah, we have not performed the farewell circumambulation (tawaf al-wada')." The Messenger of Allah (peace and blessings of Allah be upon him) said: "When the prayer is established, perform the circumambulation on your camel behind the people."
حدثنا أبو بكر قال ثنا عبدة عن هشام عن أبيه أن أم سلمة قالت يا رسول الله ما طفنا طواف الخروج فقال رسول الله صلى الله عليه وسلم إذا أقيمت الصلاة فطوفي على بعيرك من وراء الناس
